Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a ventilation structure for a dead window in an aluminum sash.

[Conventional technology]

 A conventional ventilation structure for a deadening window will be described with reference to FIG.

The drawing is a cross-sectional view, in which 1 is an aluminum sash frame, usually with a glass 2 fitted.

A blind device 3 is mounted in the upper frame 1a. 1b is a lower frame, there is a ventilation hole 4 on the outside, there is a ventilation hole 5 inside the lower frame 1b corresponding to the lower part of the blind device 3, ventilation holes 6 are connected in series, and a ventilation plate 7 is attached. A ventilation structure is formed continuously with the ventilation port 4.

[Problems to be solved by the invention]

According to the above-mentioned conventional techniques, when ventilation is particularly necessary, the ventilation holes of the ventilation plate are not sufficient, and conversely, even when ventilation is not required, ventilation is always performed by the ventilation plate. In addition, the ventilation port cannot be made large enough to reduce the adverse effect, and as a result of this, there is a problem that sufficient ventilation cannot be obtained when ventilation is required. It was

[Means for solving problems]

Therefore, in the present invention, an intermediate frame is provided in the lower part of the daylight insertion window, and the intermediate frame separates the daylighting part and the ventilation hollow part. The middle frame that encloses the ventilation hollow part, both left and right vertical frames, and the lower frame. A front plate in the shape of a slab is attached so that it covers the front surface of the frame and is flush with the peripheral end surfaces of the left and right vertical frames and the lower frame, and a mesh door is detachably provided on the inner surface of this front plate for ventilation. It is characterized in that a lid is attached to the inside of the hollow portion so as to be openable and closable.

[Action]

According to the above configuration, when ventilation is required in the room, the lid is opened to provide sufficient ventilation, and when ventilation is not needed, the lid is closed and the ventilation port is closed to prevent outside air from entering. You can

Also, when the screen door is dirty or the mesh is clogged, the screen door can be removed and taken out from the ventilation port, so the screen door can be easily cleaned and good ventilation performance can be maintained. .

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view and FIG. 2 is an enlarged sectional view. In the drawing, 8 is an aluminum sash frame, and an upper frame 9 and a lower frame 10 are shown.
An intermediate frame 13 is provided between the left and right vertical frames 11 and 12, and a blind device is attached to the inside of the upper frame 9 so that the intermediate frame 13
It is stretched between and. A space between the upper frame 9 and the middle frame 13 serves as a daylighting part, and glass or the like is fitted into the lighting part.

Further, a ventilation hollow portion 14 is provided between the intermediate frame 13 and the lower frame 10. On the front surface of the ventilation hollow portion 14, a ventilation plate 15 and a front plate 16 made of punched-out extrusion material are attached in the form of a hollow plate, and the attachment state is the intermediate frame 13, the left and right vertical frames 11, 12 and the lower frame. It is mounted so that it covers the entire front surface of the frame 10 and is flush with the front surfaces of the left and right vertical frames 11 and 12, and the intermediate frame 13 is provided by mounting plates 17 and 18 that project horizontally inward. And bottom frame 1
It is designed to be attached to 0 with screws 19 and 20, respectively.

Reference numeral 21 denotes an insect / dust-proof screen door mounted on the inner surface of the front plate 16. One side of the screen door 21, in this embodiment, the lower frame is locked to the locking portion 22 provided on the front plate 16, and the other. The side is a finger hook portion 24a of a support body 24 attached to an intermediate frame 13 that is pressed and supported by a spring 23.
It can be engaged and disengaged by holding and operating.

25 and 26 are drainage holes for draining flooded rainwater.

Reference numeral 27 denotes a ventilation port provided on the indoor side, which communicates with the front plate 16 and the ventilation hollow portion 14.

28 is a lid of this ventilation port 27, and the lower side is hinged to the lower frame 10.
It is rotatably attached at 29, and a handle 30 is attached to the upper side, and a protrusion interlocking with the handle 30 is inserted into and out of a locking hole formed in a lower frame (not shown) to lock / unlock the lid 28. 31
Is a stopper for the handle 30 and is made of an elastic material such as neoprene rubber. 32 is a heat insulating material.

According to the above configuration, first, when ventilation in the room is not necessary, by closing the lid 28 and closing the ventilation port 27, outside air enters into the ventilation hollow portion 14, but outside air is not introduced into the room. Can be stopped. This state is locked by operating the handle 30 as shown in FIG. 2, and the inner surface of the lid 28 is supported by two door stops 33a and 33b.

Next, when ventilation in the room is required, the handle 30 is operated to release the locked state, so that the lid 28 is opened toward the front as shown in FIG. The ventilation port 27 is opened by contacting with, and outside air is introduced into the room for ventilation.

In addition, when the screen door 21 of the front plate 16 is contaminated or clogged due to long-term use, the ventilation effect becomes extremely poor. Therefore, the screen door 21 can be removed by pulling the finger hook portion 24a against the force of the spring 23 and pulling the finger hook portion 24a toward you with the locking portion 22 as a fulcrum. The removed screen door 21 is taken out from the ventilation port 27 to clean the screen, inserted again from the ventilation port 27, and the finger hook portion 24a is pulled toward the front side in the same manner as described above, so that the screen door 21 is provided between the locking portion 22 and the support 24. Can be attached.

In the above embodiment, an intermediate frame is provided between the upper frame and the lower frame, and a hollow space for ventilation is formed between the intermediate frame and the lower frame so as to extend between the vertical frames on the outside of the room and horizontally Although the front plate is attached in the direction, as another embodiment, the front plate may be attached in a vertical direction on one side of the upper frame and the lower frame.

[Effect of device]

According to the present invention described in detail above, a fitting lighting section and a ventilation hollow section are provided between an upper frame and a lower frame, and a front plate of a spiral plate is attached to the front of this ventilation hollow section. A screen door is detachably installed on the inner surface of the board, and a lid is attached to the indoor side of the ventilation hollow part so that it can be opened and closed, so that it is sufficient to open the lid when indoor ventilation is required. Ventilation is performed, and when ventilation is not necessary, the lid can be closed and the ventilation port can be closed to prevent outside air from entering.

In addition, when the screen door is dirty or the mesh is clogged, the screen door can be removed and taken out from the ventilation port. Therefore, the screen door can be easily removed and taken out from the ventilation port, so the screen door can be easily cleaned. It is possible to maintain good ventilation performance.
